What should be included in the subject line of electronic correspondence?

The subject line of electronic correspondence serves a crucial purpose in effective communication by providing the recipient with a concise understanding of the email’s content. Including a clear indication of the main topic or action required allows the recipient to prioritize and quickly grasp the essence of the communication. This clarity is vital in a fast-paced environment like the Marine Corps, where effective and timely communication can impact operations and decision-making.

While a detailed summary of the correspondence may provide context, it might overwhelm the recipient with information. References to the sender's contact information are typically found within the signature block rather than the subject line, and confidentiality notes are often unnecessary for every correspondence and usually placed within the email body or footer, not in the subject. Thus, emphasizing clarity and action in the subject line enhances organizational communication efficiency and effectiveness.
